Answer:

1: two 2: wobble 3: eclipsing

Explanation:

A binary star system is made of two stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to wobble. Astronomers can also spot the dimmer star by observing a phenomenon called a(n) eclipsing binary. This happens when the dim star passes in front of the bright star.

Epinephrine has to cross the cell membrane to bind to its receptor in the cytoplasm. True or False
Vinil7 [7]

Answer:

The statement is false.

Explanation:

Epinephrine (also known as adrenaline) is a hormone and a neurotransmitter produced by the adrenal glands, it helps to regulate cellular energy metabolism and increases the heart rate.

Epinephrine adheres to certain receptors that are exposed on the surface of a large number of body cells. This receptor, called beta-adrenergic, is a receptor that is embedded in the plasma membranes of these cells. Adrenaline does not penetrate the cell, instead, joining for a short period of time to its receptor, induces it to release biochemical signals to the cytoplasm of cells. This steric change, affects the configuration of the cytoplasmic domain of the protein, this is the "link" of the receptor that protrudes in the cytoplasm.

Cellular respiration Multiple Choice oxidizes glucose and reduces oxygen. oxidizes oxygen and reduces glucose. releases energy a
vesna_86 [32]

Reduces oxygen and oxidizes glucose. A cell produces energy in the form of adenosine triphosphate (ATP) from the oxygen it takes in during aerobic respiration while also exhaling carbon dioxide and water. This is an oxidation reaction where oxygen is reduced and glucose is oxidized.

NADH contains more bonds than other molecules, and more energy is needed to maintain this molecule's integrity. Therefore, it would take more energy to break the bond while attempting to do so, making it more stable than NAD+. Aerobic respiration is the process of oxidizing glucose to produce ATP in the presence of oxygen. The following is the general equation for aerobic respiration:

Oxygen plus glucose = Carbon dioxide + Water + Energy

The breakdown of sugar and other dietary components during aerobic respiration releases energy. The Kreb cycle, glycolysis, and electron transport chain are all included. When oxygen is present, the reducing molecules NADH and FADH2 produced by glycolysis and the Kreb cycle are oxidized via the process of chemiosmosis, which reduces oxygen to water.

A strawberry farmer's crop has been devastated by a fungal infection. The farmer searches for any fungi-resistant strawberry pla
ad-work [718]

Answer:

Due to vegetative reproduction, his plants are not genetically diverse.

Explanation:

Strawberry plants do not reproduce via sexual reproduction, so we can immediately eliminate the options pertaining to sexual reproduction. Now, we can take a look at the options pertaining to vegetative reproduction.

With vegetative reproduction, the "child" plant has the same genetic makeup as the parent plant. If this happens over and over, then the offspring will not be genetically diverse. Either all of the strawberry plants or none of them would be fungi-resistant. The farmer did not find any fungi-resistant plants because they all have the same genes, and therefore all do not have the genes that would make them fungi-resistant.
